A projection system and a projection method are provided. The projection system includes a first projector and a second projector. The first projector is configured to project a first grid picture onto a projection surface. The second projector is configured to project a second grid picture onto the projection surface. The second grid picture and the first grid picture are blended into a blended projection picture. The first grid picture includes a first overlap region. Grid lines of the first overlap region are displayed in a first color. The second grid picture includes a second overlap region. Grid lines of the second overlap region are displayed in a second color. The first color and the second color are complementary colors. When the blended projection picture is formed, grid lines of an overlap region of the first grid picture and the second grid picture are displayed in a recognition color.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The projection system according to claim 1, wherein the first grid picture comprises a first non-overlap region, the second grid picture comprises a second non-overlap region, and grid lines of the first non-overlap region and the second non-overlap region are displayed in a base color.
3. The projection system according to claim 2, wherein the recognition color is the same as the base color and is white.
4. The projection system according to claim 1, wherein the first color is green, and the second color is magenta.
5. The projection system according to claim 1, wherein the first side is a right side of the first grid picture, and the second side is a left side of the second grid picture, or the first side is a lower side of the first grid picture, and the second side is a upper side of the second grid picture.
6. The projection system according to claim 1, wherein an area of the first overlap region is not greater than half of the first grid picture, and an area of the second overlap region is not greater than half of the second grid picture.
7. The projection system according to claim 1, wherein a minimum grid width of the first grid picture is equal to one pixel size, and a minimum grid width of the second grid picture is equal to one pixel size.
8. The projection system according to claim 1, wherein grids of the first grid picture are filled with black, and grids of the second grid picture are filled with black.
9. The projection system according to claim 1, wherein grids of the overlap region of the first grid picture and the second grid picture are filled with gray.
13. The projection system according to claim 12, wherein the recognition color of grid lines is the same as the base color of grid lines and is white.
14. The projection system according to claim 11, wherein the first color is green, the second color is magenta, the third color is red, and the fourth color is cyan.
16. The projection method according to claim 15, wherein the first grid picture comprises a first non-overlap region, and the second grid picture comprises a second non-overlap region, wherein grid lines of the first non-overlap region and the second non-overlap region are displayed in a base color.
17. The projection method according to claim 16, wherein the recognition color of grid lines is the same as the base color of grid lines and is white.
18. The projection method according to claim 15, wherein the first color is green, and the second color is magenta.
19. The projection method according to claim 15, wherein the first side is a right side of the first grid picture, and the second side is a left side of the second grid picture, or the first side is a lower side of the first grid picture, and the second side is a upper side of the second grid picture.
